Wow a 2011 with so much rust. I agree that these types of hard coatings are nothing but garbage. That truck would've been better off without any treatment at all. And look at all the electrical connectors, totally ruined.
But I can see how so many people go for this. It looks super clean and "professional" all while the rust is hidden away and doing colossal damage. Oil rustproofing, on the other hand, looks messy and it is messy. Even on this board I've seen people mention many times how they don't like that oil type coating attract so much dirt.
I'd rather get messy while working on my vehicles, than deal with rust.
Thanks for sharing this video, it should be an eye opener for a lot of people. This type of coating being garbage and actually causing more rust is nothing new for many of us living in the rust belt, but there are still a lot of people that fall for this garbage.
